I don’t have time right now to try earlier point releases plus this is an infuriatingly slow systembut hope this helps narrow it down a bit, at least. The output voltage generator includes a comparator, a variable resistor and a current source.

Email me about changes to this bug report. A voltage generating apparatus is provided. The disclosure can then be used to transmit high quality positional multichannel audio at a minimal wireless bandwidth.

The disclosure provides a switchable filtering circuit and the related operation method, in particular related to a filtering circuit which can be used for Bluetooth system and wireless local area network system. A low dropout voltage regulator is provided. The isdc modulation circuit includes a low frequency oscillator and low frequency mixers. A few other observations: The present invention relates to an adaptive, vluetooth efficient, power-saving apparatus for wireless communication systems, such as but not limited to Bluetooth BT receivers, and in particular to a packet-based receiver’s decoding algorithm which can detect the presence or absence of the adjacent channel interference ACI before the scheduled starting time for receiving a Bluetooth packet, and accordingly set the receiver configurations including the filter’s pass-band bandwidth BWfilter’s order, the sampling rate, the number of analog-to-digital-converter ADC output bits, and the automatic-gain-control AGC algorithm unit to determine the low noise amplifier LNA and variable gain amplifier VGA settings.
